Question

What can Amber do to make sure no one else can access her document? O Use password protection. O Add editing restrictions. O Use Hidden text. O Mark it as final.​

Answer 1

Add a password.

The question is asking how to make sure no one can “access” it which means look at it at all. This means that Editing restricting still allow people to access it, white text does nothing but make the text invisible, and marking it as final still gives them access

Answer 2

Use password protection.
